Numerical Calculation of Solidification pipeline in Gathering Lines under Carbon Dioxide Flood

摘要：

　　Under constraint conditions of freezing point of crude oil and wellhead back pressure,the mathematical models of the solidification pipeline in the gathering lines under carbon dioxide flood were set up,and the relevant numerical calculation methods were given.Taking 5 oil wells,such as S378-J245 well in the Dong 14 of Yushulin Oilfield of Daqing Oilfield and etc,as examples,the solidification pipeline in the gathering lines was calculated by the mathematical models and the numerical calculation methods mentioned above.The results show that the gathering lines under carbon dioxide flood are more possible to be solidified than that under water flood.
